This is not really a do-it-yourself project. First of all you didn't say what is wrong with the compressor. If the system is still full of refrigerant you will need to have a shop recover it. After the old one is unbolted and the new one is installed you'll need to inject some clean refrigerant then perform a leak check on the system. Then you recover that refrigerant, pump the system into a vacuum for at least a half hour, then inject the correct amount of refrigerant.
If you're installing a new or rebuilt compressor you will have to add the correct number of ounces of the correct oil. If the refrigerant was leaked out of the system and it has been empty for a while moisture will have gotten inside. That will mix with the new refrigerant and become corrosive.
Professionals wear safety glasses, gloves, and a face shield when working with refrigerant. If it escapes it can cause blindness and frostbite.
